Waking up from his definitely peaceful sleep...Killer witnessed a far less peaceful sight when facing the reality of what he called 'life', and also finding out he was going to be used as a sacrifice for a cult's summoning as he squinted his eye sockets at the occasional bright red light, or flinched at any loud chanting he happened to hear in the organized sacrificial space. Well, long story short, Killer just ended up killing them all and his problem then was really only a random whiter, bright light blocking his vision. That "peace" was all about five minutes ago. Maybe ten or even twenty, Killer couldn't tell anymore.
Now, Killer was standing face to face with whatever deity had been summoned. Looks like he accidentally made his own sacrifice with the cult members... And, it was more than necessary, so now it was a whole new deity from what the cult even tried to summon... That deity just so happened to be you. Whoops..
